Berryman 2640 4-Step Professional Air & Fuel System Maintenance Kit

I used it on my 2013 Volvo S60 T5. After this treatment my engine stopped burning oil. I'm going to perform this cleaning every 2 years on cars that are 10+ yrs old.

System worked great other than Sensor cleaner (step 1). The straw would but mate with the cleaner can. Ether the straw is to big or nozzle hole is to small. I used without.

Works great! Made my old van run like new! The van had a rough idle and the service engine light would blink if the car sat at a red light for too long. I was getting codes for 'random misfire' and 'cylinder 6 misfire'. These vans do have a lot of trouble with head haskets and intake gaskets, but the intake gasket was done about a year ago and the entire engine was replaced in 2015. The van had needed a new idle speed control motor and when I replaced it I noticed that the pintle was severely coked up. I knew that an upper intake and throttle body cleaning was due. The van had belonged to an elderly couple before I purchased it in 2017 and I am guessing it took a lot of short trips and was not warmed up all the way often enough. After purchasing the kit I followed all the directions to treat the engine. I did do one thing differently. For step 2 I ran the cleaner through the throttle body, but I also removed the idle speed control motor and ran the cleaner through that passage as well. That might be helpful if you know that the idle passage is coked up. Anyhow the van runs very well now, has much better acceleration, and idles smoothe as butter. After driving the van for about 30 minutes the check engine light went out and all is well.

I'll have to give this a good review, I've used this for my 96 Tacoma. I've had the truck since early 2000, and I've not necessarily been kind to it. Used this product per the instructions, by the third step, I could hear a difference in the idle. After finishing up the kit, I did need to reset the check engine light, (mass air flow) not a big deal. Anybody who has a Toyota knows they are picky on the MAF sensor. But it was idling higher than before, had to back the idle off by 500 to 600 rpm. Didn't realize I'd adjusted it that much over the years. So I'd think that just that alone would regain enough fuel mileage to pay for its self in no time. I live in the mountains of western North Carolina, a lot of steep grades to pull,, and with over 256,853 miles on the engine I'm excited to really get out and see what the long term results will be.

Followed the simple instructions,250k miles, frequent misfire codes on cold weather starts only. Suspected throttle body. Confirmed. Problem stopped after this treatment. Have now added this to a more frequent PM.

I’ve used this 4-part cleaning kit in two of my vehicles now. On one car it helped clear an engine code, and the other was just for preventative maintenance. Both cars run smoother and start easier. The directions are straightforward and you only need modest skills to use the cleaners.

Dealer wanted a lot of $$$ to do this exact same thing. Was very easy to do myself. I did not notice a performance difference but it did clean out a lot carbon build up.

Well, first of all, the little 6oz can of mass airflow cleaner was completely empty on arrival. Fortunately, I had some on the shelf. Second, I can't say if the intake valve chamber cleaner did much. There was no hesitation in the engine during the process, no extreme smoke, just a tad from the chemical being used as I could smell it. My car always runs great, gas mileage fell a couple of gallons so just doing pre-maintenance. Still give this 3 stars because some cars don't carbon up as some others do, so I may not have needed it.
